Salts formed by the combination of a strong acid and a strong base result in a neutral pH. This occurs because the strong acid (e.g., hydrochloric acid, HCl) and strong base (e.g., sodium hydroxide, NaOH) react completely in a one-to-one ratio, leading to the formation of water and a salt (e.g., NaCl). The resulting salt solution neither contributes to acidity nor alkalinity, yielding a pH of 7.0, which is considered neutral. The complete neutralization of the strong acid and base ensures that no excess hydrogen ions (H⁺) or hydroxide ions (OH⁻) are present in the solution, resulting in a neutral pH.
